Specification of Letters Patent.

To all whom it may concern:

Be 1t known that I, EUGENE S. Mronuuna;

a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Internal Combustion Engines, of which the following is. a specification.

The present invention relates to improvements in internal combustion engines, and is specially designed for use in connection with gasolene motors of auto-vehicles.

The object of the invention is the provision of means for admitting additional and auxiliary air-to'the intake pipe of a'gasm lenc engine between the carhureter and the engine, and for mixing the additional charge of air with the mixed fuel gas as it passes from the carburetor to the engine. The re sults of admitting this extra charge of air to the intake pip are numerous and advantageous, in that the eliieicney of the charge may be determined with relation to the load Without changing the adjustment of the carburetor, For instance, it is Well uinlerstood in this'art that a correct mixture of gasolene and air to develop the greatest possible power under heavy loads, in the engine, is far too rich for light loads, and consequently the proportion of gasolene and air must be varied to suit the differentcxisting conditions. Resort to adjusting the carburetor to suit these conditions is objectionable and undesirable. But with my auxiliary device, the proportion desired in the mixture may be varied in a simple manner without disturbing the carburetor.

The invention consists in certain novel combinations and arrangements of parts in connection with an internal combustion engine as will be more fully described and pointed out in the following.

In the accom 'ianying drawings I have illust'ated the invention according to the .best modc I have so far devised for the practical application of the pinciplcs and such embodiment has proved highly satisfactory in actual use.

Figure 1 is a view of so much of an automobile and gasolene motor as is necessary to illustrate the application of the invention. Fig. 2 is an enlarged View, in side clevalion, showinglhc invention applied to the intake pipe or manifold, above the carbureter. Fig. 3 is a top plan view of Fig. 2,

several engines oi the automobile mot.

partly broken away for convenience or innstration, and Fig. e is vertical sectional view or Fig. 2 With the device detached.

In the drawings 1 illustrated the invention applied to an automobiie motof well known standard time, to i 4.10 A ""1 pipe or manifold l. or which it attached. conventional v indicated, from which manifold extends, and is connected nin the preferred embodiment 0:5 vention I brass, including the cup 5 formed v. small upper opening 6, the inte tubular extension or sleeve Loos-ted vorsely within the sleeueris a valve of usual or suitable type and the stem 5 the plug is provided with a notched positioned outside the slee'ige i. The sum Zu 9, as seen clearly in Fig: 1 extends back from the motor and is passed through the l board 11 of the automobiie, a plate 12 he indicated as a bearing plate. The valve, through its store, may he tamed by means of? the handle 13.

The sleeve? is fashioned with a extension 14, and the extension is sate threaded adapted to be in threaded opening 15 of Saddle l the open end of the extension 1%- a cone shaped screen 17 of suitable gauze mesh, and this screen, when in prone-L position, projects across the bore of the take pipe 2 as shown in Fig. 3 for instance The intake pipe is perforated for the reset tion of the screen, and when the screen is projected across the intake pipe as shown, the. entire device is securely held to tie take pipe means of bracket 19, whose threaded prongs are pas through. the perforated ears 20 of the sad 16 and secured to the. saddle by" niesns the nuts 21.

The flow of air through the device regulated from the handle 13 or the seen 9 and. the valve may be l id in adjusted cosh tion by means of the spring; catch or o- 22 which engages the toothed dish 10 on valve stem. When the valve is open, passes through the cup 5, valve 8, sleeve *4" and through the into intake pipe. The admission of the air through screen. in the form of a spray, remixes the gesol e globules as they come from the ca-rhureter,

employ casting, preferably of tion cut oil, the valve 8 may be entirely lion, What and desire to secure by Patentis lene into the cup 5, will he an I enginesdraw' the pure air through cup and the charge is thus increawl in own, and economy In consumption of one is cll'ected.

For the purpose of priming the gamlcnc en 'nes, the cup 5 is specially well. adapted,

W en difficulty is experienced in s the motor, by pouring a few dm 1 upon cranking the motor, with the open say two notches, the engine will he fectivelyprimed for starting.

When coasting downgrade, with the ignilike" but the throttle closed, the suction of h valve into the cylindes, thus pencilting the motor to not as a brake as will be :nnderstood, and effecting a thorough cool.-

i of the cylinders. e ofjthe serwns problems to overcome rigthe useof devices of this character is to charge to the cylinders with the minimum resistance. But by using my de vice it is possible to reduce the air resistance to aminimum without sacrificing the starting 0: low speed adjustment of the carburetor, and compensation for altitude may be readily made without disturbing the pro firtanged carburetor adjustment.

8 -Having thus fully described my inven 1. The. combination with the perforated intake pipe of a gaaolene engine of a sleeve '0 eni mtmlaid rforated. i e, a screen cfising the. sleeve h nd and l ted within said-pipes valve in thesleeve, and an open cup integral withsaid sleeve, means for securing the sleeve tosaid' pipe, and means for "controlling said valve.

2.= Tho combination with the perforated '1 hintalte pipe of a gasolene engine, of a sleeve names:

hlving a reduced three ad extension opening into said pipe, a saddle perforated and threaded to receive said extension and formed with perforated cars, a clip having its ends secured in said ears for attaching the saddle to the pipe, a conical screen on the extension located inside the pipe, and a alve and actuating means therefor in said sleeve.-

3. The combination with the. perforated intake pipe of a gasolene engine, of a sleevfii a reduced threaded extension, a periddlc attached to the pipe to reextension, a conical screen on the n in the pipe, a valve in said sleeve, stern, a notched disk on said stem, and a spring detect engaging said disk.

' intake pipe of a gasolene engine, of a sleeve with a threaded extension, a perforated saddle attached to the pipe to receive said exand a conical gauze screen closing the opening of said extension) In testimon whereof I aflixmy signature in presence 0 two witnesses.
